A new soft switching bridgeless PFC converter with lossless snubber [PDF]
Increasing use of rectifiers causes harmonics pollution in networks. So use of power factor correction (PFC) in converters is inevitable. For reducing weight and volume of converters, designers try to increase switching frequency. The switching losses and conduction losses are two sources of losses in the switching power converter. Thus to reduce these
